Portable hot wire anemometer for measuring mean air speed (va).
ESV107-307 measure the air speed only, using one sample every 100 ms and update output every one sec. The ESV307 model is similar to the ESV107 model, but its output is serial to be connected directly to the RS232-2 port of the E / M-Log data loggers.
ESV306 calculates also turbolence intensity (TU) in compliance with ISO7726 using air speed measurement sampled every 100 ms, a rate allowing calculation of Average air speed (va), standard deviation and Turbulence index over 1 second. The rea
